LKG1K272MESBBK

The LKG1K272MESBBK is a snap‑in, large‑can aluminum electrolytic capacitor from Nichicon’s LKG series designed for audio equipment and high‑fidelity applications. It delivers 2700 µF capacitance at an 80 V rating with performance characteristics tailored for audio circuitry.

Built for polarized, snap‑in mounting in radial can packages, this part combines a compact φ30 × 45 mm can with a ripple capability and endurance specification suitable for professional audio systems and related electronics operating between −40 °C and 85 °C.

Key Features

• Capacitance & Tolerance — 2700 µF nominal (2.7 mF) with a tolerance of −20% to +20% at 120 Hz, 20 °C, providing defined energy storage for audio smoothing and decoupling.
• Voltage Rating — 80 V rated voltage for higher‑voltage audio circuits and power stages.
• Low‑frequency Ripple Handling — 3.6 A ripple current (120 Hz) to support demanding low‑frequency filtering and power delivery in audio amplifiers.
• Loss Tangent (tan δ) — tan δ = 0.25 measured at 20 °C, 120 Hz, enabling predictable dissipation behavior for design margin calculations.
• Leakage Current — Specified leakage current of 1390 µA for predictable standby and quiescent behavior after voltage application.
• Temperature & Endurance — Operating range −40 °C to 85 °C with a rated lifetime of 1000 hours at 85 °C, suitable for stable long‑term operation in audio environments.
• Package & Mounting — φ30 × 45 mm radial can, snap‑in mounting, packaged in trays for production handling and assembly.
• RoHS Compliance — Compliant with RoHS requirements as specified for the LKG series.

Typical Applications

• High‑Fidelity Audio Equipment — Use as bulk energy storage and smoothing in power supplies and output stages where audio fidelity is prioritized.
• Audio Amplifiers — Filtering and decoupling in amplifier power rails to support low‑noise, stable power delivery for improved audio performance.
• Professional Audio Electronics — Suitable for mixers, preamps, and other professional gear requiring stable capacitance and ripple handling at elevated voltages.

Unique Advantages

• Designed for audio quality: Series design emphasis on high‑fidelity audio makes this capacitor appropriate where sonic characteristics matter.
